A (3+1)-dimensional nonlinear evolution equation with multiple soliton solutions and multiple singular soliton solutions

ZIn this work, a (3 + 1)-dimensional nonlinear evolution equation is investigated. The Hirota's bilinear method is applied to determine the necessary conditions for the complete integrability of this equation. Multiple soliton solutions are established to confirm the compatibility structure. Multiple singular soliton solutions are also derived. The resonance phenomenon does not exist for this model.
